Definitions

  • the object of the invention is a new circularly polarized antenna, designed especially for emissions in which it will require a significant isolation between the transmit and receive antennas, as in the case of gap-fillers for the TDT reissue (digital terrestrial television), in which the transmission and reception frequency is the same.
  • circularly polarized antennas are already known, both for modulated frequency band broadcasting (for example U8900950) and for satellite location or communication systems (for example, the patent). EP0512876 ).
  • the object of the invention is a new circularly polarized antenna designed especially for emissions where it will require a significant isolation between the transmit and receive antennas, which gives rise, in circular polarization, to a radiation pattern of revolution around an axis (e1) -see figure 2 -.
  • the dipole body (5) is fitted in this reflecting screen (1): adjustments (51) each arranged on each flat face of the screen (1) -see figures 3 and 4 and all suitably isolated (9) and in contact with the mass (10).
  • the reflective screen is troncopyramidal (1), has two visors (11a), (12a) incorporated, having a closed configuration, which emerge orthogonally towards the outside thereof, respectively escorting the perimeters of said windows ( 11), (12).
  • a cover (4) which hides the outside of the base plate (2), the connectors (C 1 ), (C 2 ) and the rear area other components of the antenna.
  • the circular polarization direction indifferently on the right or on the left, is configurable externally according to the needs of each TDT retransmission system, insofar as the two connectors (C 1 ), (C 2 ) are coupled, respectively, an input / output signal (I / O) and a load resistor (RC) or vice versa.
